摘要
轮边电机驱动具有更高效的传动效率,更好的空间利用率,更快的能量回收能力。但是由于轮边电机的扭矩波动而产生的电机激振力会增大汽车垂向的加速度与轮胎动载荷,从而降低了汽车的平顺性与操纵稳定性。为了改善轮边驱动电动汽车的悬架动态特性,进行了轮边电机结构布置的优化设计。仿真结果表明,车身减振型轮边驱动系统改善了悬架的动态特性,提高了汽车的平顺性和操纵稳定性。
The wheel-side motor drive has more efficient transmission efficiency,better space utilization,and faster energy recovery capability.However,the motor excitation force generated by the torque fluctuation of the wheel motor will increase the vertical acceleration of the car and the dynamic tire load,thereby reducing the ride comfort and handling stability of the car.In order to improve the dynamic characteristics of the suspension of the wheel-driven electric vehicle,the optimal design of the structure arrangement of the wheel-side motor is carried out.The simulation results show that the body vibration-absorbing wheel drive system improves the dynamic characteristics of the suspension and improves the ride comfort and handling stability of the vehicle.of brush seal without differential pressure,and the correctness of the model was verified by comparing with previous data.Finally,the results of numerical simulation and analytical solution are compared.The results show that the hysteresis model of brush seal under non-pressure is basically consistent with the previous data,and the error between analytical solution and numerical simulation is very small.
